Background: CT1812 is an experimental therapeutic sigma-2 receptor modulator in development for Alzheimer's disease (AD) and dementia with Lewy bodies. CT1812 reduces the affinity of Aβ oligomers to bind to neurons and exert synaptotoxic effects. This phase 2, multi-center, international, randomized, double-blind, placebo-controlled trial assessed safety, tolerability and effects of CT1812 on cognitive function in individuals with AD.

Given the desirability of a more acceptable administration route for prolonged AD treatment, we assessed the efficacy of HY209 via oral delivery. This study aims to elucidate the therapeutic potential of NuCerin, an oral formulation of HY209, in the aforementioned AD model, while simultaneously identifying potential blood biomarkers indicative of NuCerin's therapeutic action.

Participants learn new terms such as ARIA, edema and microhemorrhage and undergo numerous MRI scans for safety monitoring. They take quarterly composite Alzheimer's assessments that are anxiety-provoking and highlight weaknesses which may have been unrecognized in daily life.

The role of Natural Killer (NK) cells of the innate immune system in AD has largely been overlooked. In a murine model, depletion of NK cells augmented the accumulation of pathological α-syn.

Background: Non-human primates (NHP) serve as an important bridge for testing therapeutic agents that have been previously shown to be effective in transgenic mouse models. Our earlier published data using an NHP model of sporadic AD-related pathology that develops abundant cerebral amyloid angiopathy (CAA), squirrel monkeys (SQMs), indicates that chronic treatment with TLR9 agonist, class B CpG ODN, safely ameliorates CAA while promoting cognitive benefits. In the present study, we intended to delineate alterations in brain metabolome induced by chronic CpG ODN administration in order to provide further insight into CpG ODN immunomodulatory capabilities.
